Lexicon MX400XL 4-in/4-out Reverb Effects Processor

The Lexicon MX400XL is a 4-in/4-out dual stereo and surround reverb processor built around 35 of Lexicon's acclaimed algorithms, encompassing reverbs, delays, modulation effects, and dbx dynamics processing. Operating at 24-bit resolution with selectable 44.1kHz or 48kHz sample rates, it delivers the polished, dimensional sound that has made Lexicon a staple in professional recording studios and live sound rigs. The 224 factory presets — including 25 surround-specific programs — provide immediate access to a wide variety of effects tailored for music production, broadcast, post-production, and live performance.

What sets the MX400XL apart from typical outboard processors is its USB "hardware plug-in" feature. When connected to a computer via USB, the included VST and Audio Units plug-in software lets you control the MX400XL directly from within your DAW, effectively turning a piece of hardware into a software-integrated effects unit. This hybrid approach gives engineers the tactile warmth and reliability of dedicated hardware with the recall and automation convenience of a plug-in. All audio connections are balanced XLR, ensuring clean signal transfer in professional environments, and the backlit LCD with intuitive front-panel controls makes standalone operation straightforward during live shows or tracking sessions.
